When this is accomplished, however, may be used as substitutes and any the ends of the hood may be properly united changes made within scope of the claims. by any suitable meanssuch as is shown in Fig. 3, where the contiguous ends are formed into a lock joint or seam at the point Where they meeteach end being flanged in a hook form in the opposite direction to the other and adapted to interlock with the flange of the opposite end, although it is evident that the free ends of the hood need not be united by so locking them together, but may of course be united by a third interposing member. In this connection both in the specification and claims the word unite is used broadly to cover any suitable means for uniting the ends of the hood. v

Having thus described my invention, what I claim is 1. In a stereoscope, a hood having a plurality of raised pockets, and a lens-frame having raised portions corresponding to the pockets of the hood and adapted to engage therein and means adapted to unite the ends of said hood.

2. In a stereoscope, a hood havinga plurality of raised pockets and a lens-frame having a plurality of binding members secured on its periphery and adapted to engage with the pockets on the hood to secure the said hood 'and lens-frame from any movement in relation to each other and means adapted to unite the ends of said hood.

3. In a stereoscope, a hood having a series of raised pockets or beads adjacent to its forward edge, a lens-frame, and means carried by the latter adapted to engage with the raised pockets in the hood to prevent relative movement between the hood and lens-frame and means adapted to unite-the ends of said hood.

4. In a stereoscope, a hood having a plurality of raised pockets, and a lens-frame having raised portions corresponding to the pockets of the hood and adapted to engage therein, and means adapted to secure the ends of said hood.

5. In a stereoscope, a hood havinga plurality of raised pockets and a lens-frame having a plurality .of binding members secured on its periphery and adapted to engage with the pockets on the hood to secure the said hood and lens-frame from any movement in relation to each other, and means adapted to secure the ends of said hood.

6. Inastereoscope, a hood having aseries of raised pockets or beads adjacent to its forward edge, a lens-frame, and means carried by the latter adapted to engage with the raised pockets in the hood to prevent relative movement between the hood and lens-frame, and means adapted to secure the ends of said hood.

7 In a stereoscope, a hood having aplurality of projecting pockets adjacent to its forward edge, and a lens-frame having raised portions corresponding to the pockets of the hood and adapted to engage therein.

8. In a stereoscope, a hood forming one member, a lens-frame forming another member, a plurality of raised pockets on one of said members, corresponding raised portions on the other member adapted to engage in the said pockets, and means adapted to unite the ends of the said hood.
